Federal Reserve Governor Chris Waller used a June 25 conference to recast stablecoins as a monetary policy problem rather than a crypto-sector curiosity, arguing that the rapid growth of dollar tokens like $USDC and $USDT is now large enough to register in T-bill demand, bank funding conditions, and the Fed's own balance-sheet plumbing.
Why it matters
Waller's framing is the closest a sitting Fed governor has come to treating stablecoin issuance as a parallel short-term funding market. Every new dollar token is, mechanically, a buyer of short-duration Treasuries and a substitute for traditional bank deposits. That puts stablecoins inside the same plumbing the Fed watches when it sets the floor under money-market rates and the ceiling on the reverse repo facility.
Market impact
The signal is reputational more than mechanical today, but the trajectory matters. Tether and Circle together hold tens of billions in T-bills, and the GENIUS Act pathway in the US plus Europe's MiCA framework are pushing issuance further onto regulated balance sheets. If stablecoin float keeps compounding, Waller's concern stops being theoretical: a stress event in tokenised dollars would land on the same desk at the Fed that handles a Treasury market dislocation.
Frequently asked questions
-
What did Fed Governor Waller say about stablecoins?
At a June 25 conference Waller argued stablecoins are large enough to register in T-bill demand, bank funding, and dollar liquidity, effectively moving them from a crypto-sector topic onto the Fed's policy desk.
-
Why are stablecoins a concern for T-bill markets?
Every newly minted stablecoin is mechanically a buyer of short-duration Treasuries, so growing issuance shifts marginal demand at T-bill auctions and competes with bank deposits for short-term dollar funding.
-
How much in T-bills do Tether and Circle hold?
Tether and Circle together hold tens of billions of dollars in T-bills, making stablecoin issuers among the larger marginal buyers of short-duration US government debt.
-
How does the GENIUS Act affect stablecoin demand for Treasuries?
The GENIUS Act pushes US stablecoin issuance onto regulated balance sheets with stricter reserve rules, which channels more issuance into T-bills and deepens the link between stablecoin float and Treasury demand.
-
Could a stablecoin stress event affect the Fed?
Waller's framing suggests yes: if tokenised dollars are inside the Fed's funding-plumbing perimeter, a run on a major stablecoin would reach the same desk that handles a Treasury market dislocation.
